Don’t worry about it too much, just do not use it near a candle or other open flame. It doesn’t spontaneously combust. The flammability range is between 2 and 12.7% of vapor in air. While in the bottle, stored away from heat and naked flame it is quite safe. The odorless thinners are also flammable, as is acetone, all need to be stored in cool place, in securely closed containers, away from open flame and heat.

My son used to use “Simple Green” to strip his warhammer models. A few weeks ago I was stripping a head.I had “Mean Green” from dollar tree (not sure if it’s the same). That stuff about stripped everything right off. This was a practice head not too sure what I did to it. I did have to scrub the sealer a bit because i could see it and work on the creases Then I washed as usual. Both products are supposed to be safe-health wise
